我现在用一个控件，但是如何取得编辑框的数据呢？请高手指点，该控件代码如下：
1<object class="tbContentElement" classid="clsid:2D360201-FFF5-11D1-8D03-00A0C959BC0A" height="80%" id="tbContentElement" viewastext="">
2<param name="ActivateApplets" value="0"/>
3<param name="ActivateActiveXControls" value="0"/>
4<param name="ActivateDTCs" value="-1"/>
5<param name="ShowDetails" value="0"/>
6<param name="ShowBorders" value="0"/>
7<param name="Appearance" value="1"/>
8<param name="Scrollbars" value="-1"/>
9<param name="ScrollbarAppearance" value="0"/>
10<param name="SourceCodePreservation" value="-1"/>
11<param name="AbsoluteDropMode" value="1"/>
12<param name="SnapToGrid" value="0"/>
13<param name="SnapToGridX" value="50"/>
14<param name="SnapToGridY" value="50"/>
15<param name="UseDivOnCarriageReturn" value="0"/>
16</object>

1<form <input="" id="ttim" name="htmlcode" type="hidden" value="">
2<input onclick="javascript:htmlcode.value=tbContentElement.DocumentHTML;form1.submit();" type="button" value="提交"/></form>
